Processes and Procedures in the Extraction of Iron

This iron can also be used in steel production or purified further to give wrought iron. Waste gas mixture that exudes from the furnace contains majorly nitrogen, 30 carbonIIoxide and about 10 carbonIVoxide. These waste gas mixture is used in pre heating the air blast and the iron ore at the initial stages of the extraction process.

Extractive Metallurgy of Nickel, Cobalt and Platinum Group

Solvent extraction occurs in at least two steps: extraction and stripping. The aqueous solution from the extraction stage is known as the raffinate andanic from the extraction stage is known as the loaded organic. In practice, extraction and stripping are each done in several mixer settlers connected in a counter current manner.

07/03/2010· During the extraction of iron, the reduction of iron oxides takes place in a blast furnace. In this process, hot air is blown from the bottom of the furnace and coke is burnt to raise the temperature up to 2200 K in the lower portion itself. The temperature is lower in the upper part. Thus, it is the lower part where the reduction of iron oxides Fe2O3 and Fe3O4 takes place.
